-===== General =====
+==== Changing the collection description ====
+The collection's description - shown on the about page - generally comes from the 'description' displayItem in the collection's collectionConfig.xml file. This can only hold text and html. Sometimes you might want to do more in the description.
+The place where the description gets printed out is in the about page XSL: web/interfaces/default/transform/pages/about.xsl.
+There is a template called coll-description:
+<code>
+<xsl:template name="coll-description">
+   <gslib:collectionDescriptionTextAndServicesLinks/>
+</xsl:template>
+<code>
+<gslib> elements are shortcuts to predefined templates, and can be found in web/interfaces/default/transform/gslib.xsl.
+Lets leave the collection description displayed as is, but output "This collection contains X documents, and was last built on Y".
+We can redefine the template as:
+<code>
+<xsl:template name="coll-description">
+   <gslib:collectionDescriptionTextAndServicesLinks/>
+   <xsl:variable name="raw_date"><gslib:collectionMeta name="buildDate"/></xsl:variable>
+   The collection contains <gslib:collectionMeta name="numDocs"/> documents, and was last built on <xsl:value-of select="util:formatTimeStamp($raw_date, 0, 0, /page/@lang)"/>.
+</xsl:template>
+<code>
+<gslib:collectionMeta> can retrieve metadata elements from the collection (as opposed to from documents).
+The buildDate metadata element is a timestamp, so is not user friendly. We can use one of our utility functions to format it.
